STITCHED BUTTONH-OLE.

Specification of- Letters Patent To all whom it may concern Be it known that I, GEORGE S. HILL, a

citizen of the United States, residing at- Straord, in the county of Stratford and State of New Hampshire, have invented certain new and useful Improvements in Stitched-Buttonholes; and I do hereby declare the following to be a` full, clear, and exact description of the invention, such as will enable others skilled in the art to which it Aappertains toI make and use the same.

The invention relates to stitched buttonholes such as are formedin the buttonhole pieces of but-ton boots 0r in other fabrics orrarticles.

The object of the invention is to provide a'novel and improved stitched buttonhole in which 4the end of the thread leading'to the initial stitch of the overedge seam which extends about the edge of the buttonhole is securely anchored, thus avoiding raveling or'loosening of the seam at this point, and also avoiding the necessity of trimming or cutting away a waste end of thread after the stitching of the buttonhole has been completed.` To this end the invention contemplates covering the free end ot the thread which leads to the initial stitch of the seam by the vstitches of the seam. IVith the free end of the thread thus covered. the seam is given a better finish, and is also stronger, since the end ofthe thread is so held and anchored that itI cannot ravel or pull outI of the seam.

The invention will be readily understood from an ins ection ofthe accompanying drawings and the following detailed dcscription of the buttonhole illustrated therein and the manner in which it is formed.

In the drawings. Figure 1 shows a buttonhole slit and the position in which the free end of the needle thread is held at the lbeginning of the sewing; Fig. 2 shows a buttonhole after a number of stitches at the beginning of the seam have been formed; .and Fig. 3 shows a completed buttonhole.

In the drawings the invention is shown as embodied in a buttonhole such as is made by the machine of Patent No. 1,063,880,

stitches about the edge ofthe buttonho'le slit are formed by upper and under needles, the upper needle piercing the material to formthe depth stitches, and "the 'runder yneedle passing up through the but-tonhole slit. In forming the buttonhole embodying the present invention the free end 2 of the upper thread `whichextends beyond the eyeof the upper needle is held at. the beginning ot' the sewing in substantially the position.

indicated in Fig. 1. When thus held, the thread leading to the initial needle hole lies between the edge of the buttonholeslit 4 and the path of the upper needle 6 in forni ing the initial stitches 8 of lthe seam. As thesewing of the seam continues, the freey or waste end of the thread is therefore covered by the stitches which lead from the depth needle holes over the edge of the buttonhole slit, so that in the completed buttonholethis end of the upper needle thread is covered and concealed by the stitches of the seam, as indicated in` Fig. 3. The free end of the upper thread leading to the initial stitches of the Seam is thus anchored and held so that it cannot draw out of the needle hole` and consequently the seam is strengthened and rendered more durable at this point. The covering of the end of the thread also gives a better finish to the seam, and avoids leaving a short. waste end projecting from the initial needle hole on the finished side of the work, which must betrimmed or cut away after the but-tonhole has been completed.

Vhile theA invention has been shown and described with l'ci'crcnce to a but-tonholc the ovcr-sean1 stitching ot' which is formed by upper and under |h1eads.-it will bc understood that it is not contincd in its application to this form ot' over-scam stitching. butmay be embodied in butlonholes which are stitched with other forms ot' over-seams.

Having explained thc nature and object ot' the invention, and specifically described one form of buttonhole in which it may be embodied. what. is claimed is 1. A stitched buttonhole comprising the material in which the buttonhole is formed, and an over-seam about the edge of the buttonhole having the 'end of the thread Patented Aug. 18, 1914.'

leading to the initial stitch located between and having the upper thread which leads to the face of the material and the stitches of the initial stitch covered by -the initial the overseam. stitches 'of the seam.
